    • Analysis of composition, morphology, and biosynthesis of cuticular wax in wild type bilberry (Vaccinium myrtillus L.) and its glossy mutant 

      Trivedi, Priyanka; Nguyen, Nga; Klavins, Linards; Kviesis, Jorens; Heinonen, Esa; Remes, Janne; Jokipii-Lukkari, Soile; Klavins, Maris; Karppinen, Katja; Jaakola, Laura; Häggman, Hely (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-09)
      In this study, cuticular wax load, its chemical composition, and biosynthesis, was studied during development of wild type (WT) bilberry fruit and its natural glossy type (GT) mutant. GT fruit cuticular wax load was comparable with WT fruits. In both, the proportion of triterpenoids decreased during fruit development concomitant with increasing proportions of total aliphatic compounds. In GT fruit, ...

    • Compositional and morphological analyses of wax in northern wild berry species 

      Trivedi, Priyanka; Karppinen, Katja; Klavins, Linards; Kviesis, Jorens; Sundqvist, Petri; Nguyen, Nga; Heinonen, Esa; Klavins, Maris; Jaakola, Laura; Väänänen, Juha; Remes, Janne; Häggman, Hely (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-21)
      Aerial surfaces of plants are covered by a waxy cuticle protecting plants from excessive water loss and UV light. In the present study, composition and morphology of cuticular waxes of northern wild berry species bilberry (<i>Vaccinium myrtillus</i> L.), lingonberry (V. <i>vitis-idaea</i> L.), bog bilberry (V. <i>uliginosum</i> L.) and crowberry (<i>Empetrum nigrum</i> L.) were investigated. Scanning ...

    • Temperature has a major effect on the cuticular wax composition of bilberry (Vaccinium myrtillus L.) fruit 

      Trivedi, Priyanka; Klavins, Linards; Hykkerud, Anne Linn; Kviesis, Jorens; Elferts, Didzis; Martinussen, Inger; Klavins, Maris; Karppinen, Katja; Häggman, Hely; Jaakola, Laura (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-20)
      Cuticle is the first layer protecting plants against external biotic and abiotic factors and is responsive to climatic factors as well as determined by genetic adaptations. In this study, the chemical composition of bilberry fruit cuticular wax was investigated through a latitudinal gradient from Latvia (56◦N 24◦E) through Finland (65◦N 25◦E) to northern Norway (69◦N 18◦E) in two seasons 2018 ...

    • Trace element concentration and stable isotope ratio analysis in blueberries and bilberries: A tool for quality and authenticity control 

      Klavins, Linards; Maaga, Inessa; Bertins, Maris; Hykkerud, Anne Linn; Karppinen, Katja; Bobinas, Česlovas; Nguyen, Nga; Salo, Heikki M.; Salminen, Henriikka; Stankevica, Karina; Klavins, Maris (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-09)
      Vaccinium genus berries—wild bilberries (Vaccinium myrtillus L.) and cultivated highbush blueberries (Vaccinium corymbosum L.)—are consumed worldwide, and their consumption has a trend of stable increase. Thus, considering their wide use in ethnomedicine, for juice and jam production, as functional food, as well as their use in preparations of extracts which have application potential in pharmaceutical ...
